| vascular plants | plants with roots and stems which contain tubes for moving water through the plant. | 
| nonvascular plants | plants without stems (mosses, liverworts, green algae) | 
| petal | colorful leaf that helps attract insects | 
| pollen | Carried by wind, insects, or birds. | 
| fruit | Produced in the flower, it protects the seeds. | 
| pistil | The female part of the flower. The seed develops in the ovary at the bottom. | 
| stamen | The male part of the flower. Produces pollen. | 
| sepals | They protect the emerging flower bud | 
| stem | conducts water from the roots to the cells of the plant | 
| leaves | photosynthesis takes place here | 
| spores | ferns, mosses, liverworts reproduce with these, not seeds. | 
| embryo | baby plant, emerging from the seed | 
| dormancy | winter hibernation for plants | 
| chlorophyll | green pigment which captures sunlight for photosynthesis | 
| carbon dioxide | gas needed by plants for photosynthesis | 
| oxygen | gas given off by plants during photosynthesis | 
| sunlight | energy needed for photosynthesis | 
| leaves | part of plant where photosynthesis takes place | 
| flower | part of plant where reproduction takes place |
